Image Processing Apparatus for Generating a Combined Image from Plural Captured Images Having Been Subjected to Position Alignment, and Image Processing Method

2. The image processing apparatus according to claim 1, wherein the detecting of the specific regions comprises detecting the specific regions by using positions thereof in their corresponding images as a condition.

3. The image processing apparatus according to claim 1, wherein the detecting of the specific regions comprises detecting one of the divided regions as a specific region in a case in which other divided regions disposed so as to flank the one of the divided regions have luminances and contrasts that satisfy the determination conditions.

4. The image processing apparatus according to claim 1, wherein the detecting of the specific regions comprises detecting one of the divided regions as a specific region only in a case in which a number of the divided regions that satisfy the determination conditions is greater than a number of the divided regions that do not satisfy the determination conditions in a prescribed area centered on the one of the divided regions.

5. The image processing apparatus according to claim 1, wherein the detecting of the specific regions comprises performing expansion processing on the divided regions that do not satisfy the determination conditions and subsequently performing contraction processing thereon, thus re-determining whether or not the divided regions having been subject to the expansion and contraction processing satisfy the determination conditions.
